product features
The function of crystals is for the system to provide the basic clock signal. Usually a system share a crystals, is advantageous for the parts in sync. Some of the fundamental frequency and radio frequency communication system using different crystals, and through the electronic method of adjusting the frequency in sync.
Crystals are there in each single chip microcomputer system, the whole is called crystal oscillators, crystals in the single chip microcomputer system is very big, he combined with single chip microcomputer internal circuit, necessary to generate MCU clock frequency, all the instruction execution of single chip microcomputer is established on the basis of the crystals to provide the higher clock frequency, the faster the running speed of the single chip microcomputer is also.
Operating Temperature Range:
-20℃~70℃
Crystal Frequency & Resistance will be tested under the following conditions,
Unless extra requirments:
standard temperature(25±2℃) after heat balance.
Mechanical test:
The quartz crystal unit shall be subjected to normal atmospheric conditions for 1hr before being tested.
Dropping Test:
The Units are measured for its frequency and resistance in accordance with Table1 & without mechanical damage,after allowing the crystal to fall freely.From 75 cm of height 3 times on the firmed wood.
Vibration Test:
A. Test surface: 30mm thick hard board;
B. Drop height: 75cm;
C. Drop times: 3 times;
D. Begins to drop posture: the leading end is upward;
E. Initial and final test items: frequency, resistance
Sealing Tightness:
Find Lead Test:≤1×10-8atm·cc/S by Helium mass-mass-spectrometer detector,and vacuum and reach 1×10-3Pa；
Resistance to Soldering Heat:
The Units are measured for its frequency and resistance in accordance with Table 1 after dipping into molten solder with the temperature of 320℃±10℃；For 3~4 secs and at a depth up to a point 2.0mm from the base root.
